FIELD OF THE INVENTION

The present invention relates generally to chimneys but more particularly to caps crowning chimney tops.

BACKGROUND OF THE INVENTION

The top of chimneys are exposed to the elements and as such, get damaged. This damage can eventually be the cause of fire. To remedy that situation, it is important to regularly inspect the top of chimneys and effect the necessary repairs.

In order to minimize damage, better chimney caps have been developed over the years but they generally require the work of a skilled craftsman that cuts and folds several pieces of sheet metal in order to create a tight fitting metal cap assembly. This work is generally done on site and can be quite expensive. That is why, quite often, that step is bypassed and an unskilled worker builds a less than satisfactory chimney cap.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known devices now present in the prior art, the present invention, which will be described subsequently in greater detail, is to provide objects and advantages which are to provide a chimney sealing top which is significantly more resistant to damage and at the same time can protect the exterior surfacing of a chimney so that water does not infiltrate and cause damage.

In order to do so, the invention has a standard cap and a single-piece crown. The single-piece crown is directly attached to a chimney casing. The single-piece crown has a hole through which passes a chimney pipe. The standard cap is welded to the chimney pot. The chimney pipe passes through to the chimney pot. The standard cap is slipped over the chimney pipe and fastened onto the single-piece crown using mechanical fasteners.

Preferably, the chimney sealing cap has the standard cap further comprised of a flat part, sides, and a chimney pot extending upwardly from the flat part.

The single-piece crown is directly attached to a chimney casing by way of mechanical fasteners passing through holes made into a skirt.

The chimney pot is welded to the flat part.

In a preferred embodiment, mechanical fasteners are used for securing the single-piece crown onto the chimney casing, and the standard cap is slipped over and is fastened onto the single-piece crown by mechanical fasteners passing through standard cap holes.

Preferably, the standard cap has built-in flaps to divert water.

The one-piece construction is in-shop assembled, welded, and quality controlled, including watertight tests, something unachievable on-site. This combination of known manufacturing techniques results in a new and unexpected chimney sealing cap which has the advantages of having a final field installation that is very simple, and performed quickly by unskilled labor. Also the end product is a chimney sealing cap with a much extended life-cycle. Water and ice infiltration are eliminated which reduces damages to the chimney and its immediate surroundings.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.

Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter which contains illustrated preferred embodiments of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 Exploded view of the invention.

DETAILED DESCRIPTION

A chimney sealing cap (10) is comprised of a standard cap (12) and a single-piece crown (14). The single-piece crown (14) is directly attached to a chimney casing (16) by way of mechanical fasteners (not shown) passing through holes (17) made into a skirt (19). The standard cap is further comprised of a flat part (11), sides (15), and a chimney pot (22) extending upwardly from the flat part (11).

The single-piece crown (14) has a chimney hole (18) through which passes a chimney pipe (20). The chimney pipe (20) then goes on through to the chimney pot (22). The chimney pot (22) is welded to the flat part (11) at the manufacturing stage and is also water tested for leakage during that stage in a specialized shop.

Mechanical fasteners are used for securing the single-piece crown (14) onto the chimney casing (16). Once the single-piece crown (14) is mechanically fastened onto the chimney casing (16), the standard cap (12) is slipped over and is fastened onto the single-piece crown (14), again, using mechanical fasteners (not shown) passing through standard cap holes (13).

The hole (18) provides the added feature of a self-centering guide for the on-site assembly of the chimney pipe (20). The one-piece crown (14) fits snuggly over the entire chimney casing (16) to prevent any infiltration. While The standard cap (12) has built-in flaps (24) to further divert water.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
